Specification of Letters Patent.

Patented Apr... 13, 1915.

Application filed July 17, 1913. Serial No. 779,490.

To all whom it may concern Be it known that 1, Banner L. GAFLISOH, acitizen of the United States, residing at Clymer, in the county ofChautauqua and State of New York, have invented new and usefulImprovements in Sleds, of which the following is a specification.

This invention relates to a sled which is more particularly designed forhauling logs in lumbering although the same may also be used for otherpurposes.

it is the object of this invention to produce a sled for this purposewhich is very strong and durable in construction, which will. readilyaccommodate itself to any irregularity in the surface over which thesame is drawn so as to relieve the various parts thereof from unduestrain, and which can be produced at comparatively low cost.

in the accompanying drawings: Figure 1 is a perspective view, partly insection, of a sled embodying my improvements. Fig. 2 is a fragmentaryvertical longitudinal section of the front part of the sled taken inline 22, Fig. 3. Fig. 3 is a vertical transverse section, taken in line3.3, Fig. 2. Fig. l is a fragmentary vertical longitudinal section ofthe rear part of the sled taken in line et--i, Fig. 5. Fig. 5 is afragmentary vertical transverse section taken in line 5-5, Fig. 4. Fig.6 is a fragmentary vertical longitudinal section showing the manner ofconnecting the reach with the front bolster and beam, the section beingtaken in line 6-45, Fig. 7. Fig. 7 is a front elevation of the same.

Similar characters of reference indicate corresponding parts throughoutthe several views.

In its general organization my improved sled comprises two front runners1, 1, two rear runners 2, 2, a front beam or cross piece t mounted onthe front runners, a front bolster 5 pivotally mounted for horizontalrotation on the beam, a rear bolster or cross piece 6 connecting the earrunners, a longitudinal reach 7 connected with the front bolster andmounted on the rear bolster, a pole 8 pivotally connected with the frontrunners, and two pull rods 9 connecting the intermediate part of thereach with the rear runners.

Although the runners may be variously the construction which is shown inthe drawings. Each of the runners as there shown comprises a knee 10which. is constructed of a plank of wood arranged lengthwise and in anupright posiconstructed I prefer tion, a shoe 11 applied to theunderside of r the knee and having an upwardly turned front end, and twocheeks or blocks 12 of wood secured to opposite sides of the kneeadjacent to the upper edge thereof and about midway of its length. Theupper edge of each of the knees may either be horizontal or straightthroughout its length, as shown with reference to the rear runners inFigs. 1 and 4, or this upper edge of the knees may be turned upwardslightly at the front ends thereof, as shown in Figs. 1 and 2, or thesame may be of any other desired conformation.

On its upper part each runner is provided with a half-round bearing 13which has its axis arranged horizontally and transversely of the runnerand which is formed in the upper edges of the central part of the kneeand the checks of the respective runner.

The front beam at is preferably constructed of a piece of wood which isrectangular in cross section and provided near its 0pposite end and onthe underside thereof with half round journals 14 each of which isseated in and turns vertically in one of the half-round bearings of oneof the front runners. Longitudinal movement of the front beam in thebearings of the front runners is prevented by means of shoulders 15formed on the beam at opposite ends of the half-round journals andengaging with the outer sides of the cheeks thereof, as represented inFig. 3. The front beam is connected with the front runners in suchmanner that these parts are free to turn one relatively to the other themeans for this purpose shown in the drawings preferably comprising twopairs of upright tie coupling bolts 16 each pair having their lowerparts passing through the cheeks of one runner while their upper partsare arranged in segmental slots 17 formed in the adjacent part of thebeam journal, eyes 18 arranged at the upper ends of the tie bolts andaxially in line with the axis of the beam journal and runner bearing,screw nuts 19 arbe easily assembled and and the beam. By; this 7 10 alsopreferably constructed of a lQOe of wood which is rec-'tangularincrosssection and is provided lower near its opposite endswith two cylindrical journals-21 each of which is seated with its alf inthe half-bearing of one of the rear runners. Each rear journal isconfined .in-I the bearing of the respective runnerv by inea'ns'ofva'pair of straps of iron each of which has a half-round central part 22engaging with the upper side of the respect e cylindricalj urnal andfastening lugs 23 tll'lttllg'ed at opposite ends of the halfround part,of the strap and secured to the upper side of the adjacent check orbearing block of the runner by bolts 24', as shown in Figs. 1 and 4, orby any other suitable means At opposite ends of the cylindrical journalsof the rear bolster the same is provided with shoulders 25 which engagewith the-oute sides of the cheeks or bearing blocks andthereby preventeach of these runners and the rear bolster from beam, and 28 representsa similar a sents a' king bolt moving axially one relatively to theother. 7 Various means may be employed for connecting the front bolsterand reach and pivotally connectingthese parts with the front beam. Themeans, however, which are shown in the drawings are suitable andpreferred and constructed as follows: 26, 27 represent cooperating metalwearing plates secured respectively to the underside of the frontbolster and the upper side of the front wearing plate of metal securedcentrally to the underside of the front beam. 29 represents an uppercoupling strap of metal secured of the and projecting forwardly throughan openingf'30 in the central part of the front bolster, and 31 a lowermetal coupling strap secured'to the underside of the reach at the frontend thereof and projecting forwardly e upper side of the front end Ithereof into a notch 32 formed centrally on the underside of thefrontbolster. 33 reprepassing vertically through corresponding'openingsinthe front bolster,

T j the front beam, the coupling straps and the wear plates, and.resting with its head 34 on toward the dogs on one side top of the frontbolster. This king pin is held" against displacement by means of acotter 35 passing through the lower end of the same and engaging withthe lowermost wear plate, as shown in Figs. 6 and 7.

Upon drawing this sled over the ground each of its runners is free toturn vertically and adapt itself to the surface over which it passesindependently of the other runners owing to the independent pivotalconnection with each runner of its companion cross piece, beam orbolster, thereby preventing undue straining of the sled particularlywhen the same is heavily loaded with legs and not only permitting ofhauling the load more readily over irregular ground but also saving thesled from undue wear and tear. Furthermore, this sled is so constructedthat in the eventof any of its parts becoming broken by accident thesame can be readily repaired.

When this sled is used for logging purposes exclusively the oppositeends of the bolsters are provided with. retaining dogs which areconstructed in accordance with my invention. As shown in Figs. 1, 3ftllll 2 63th of t-lltSt dog's COHIDIISGS a horizontal ase 36 secured tothe upper side of the bolster at the, outer end thereof, an upright arm37 projecting upwardly from the base, an inner pointed retaining spur 38projecting upwardly from the arm along the inner side thereof and alaterally projecting pointed loading spur 39 arranged on the upper outerpart of the arm.

Upon rolling the logs down, askid-way of the sled the outwardlyprojecting loading spurs 39 thereof engage the surface of the logs andprevent the same from turning so that the logs can be easily rolled fromthe skid-way by means of cant hooks over the respective dogs and ontothe bolsters. After the logs have been loaded upon the bolsters theoutermost logs of the load adjacent to the dogs engage with the upwardlypointing inner retaining spurs of the dogs, thereby pre venting the logsfrom, rolling off the bolsters.

By this construction of dogs the same materially facilitate the loadingof the logs onto the sled and also retain the same upon the sled afterbeing loaded, thereby enabling the logs tobe handled and transported inless time and with greater safety than has been possible with the meansemployed for this purpose heretofore.

I claim as my invention:

A sled comprising a runner having a knee, two cheeks or blocks securedto opposite sides of the knee and constructed to form a half-roundbearing in the upper edges of said knee and cheeks, a cross piece havinga rounded journal which turns in said hearing and means. for connectingsaid, runner and cross piece comprising two tie bolts ar- Witness myhand this 2nd day of July, ranged in said cheeks and in segmental slots1913.

in cross piece and provided With eyes in line with the axis of saidbearing and journal, and a pivot pin arranged in the eyes of Witnesses:both tie bolts and supported on said cross ORA B. CAFLIscH, piece. ELsmTHOMPSON.
